No, we have no control on what happens to the graphics chip. It's
shutdown by the PMU. When we wakeup, if the gfx chip is dead, there's
nothing much we can do.

For ATI based, there is hope that they provide us with the necessary
tables & code bits to do the chip bringup on wakeup, though it's not
100% sure and it takes time (they provided the code for waking up the
chip on earlier laptops, though that took about 6 monthes, but they
did it in the end).
